Hi guys, i am moving to a new address that's served by optimum online. For TV, i want to get the cheapest package (just basic channels + their HD counterparts).
The prime mover for flexion of the shoulder muscles used are the following: 1  Pectoralis Major Clavicle. 2  Anterior Deltoid. 3  Biceps Brachii Short Head. 4  Coracobrachialis.
Shoulder flexion requires an optimal length of the latissimus dorsi muscle in order to allow full lateral rotation of the humerus and upward scapular rotation. If shoulder flexion (in an externally rotated position) is restricted, this may predispose the individual to shoulder pathology.
